The Tjernlund UC1 Control Board is a high-performance universal control designed to manage the sequence of operation for power venters and draft inducers. This essential HVAC component ensures that the combustion air system is functioning correctly before allowing the burner to ignite, providing a critical safety interlock for furnaces, boilers, and water heaters. Featuring advanced modulating capabilities, it helps maintain optimal exhaust flow and prevents the accumulation of hazardous flue gases. The board includes diagnostic LED indicators for easy troubleshooting and adjustable pre-purge and post-purge settings to customize performance based on the specific venting requirements of the appliance. Whether you are performing a repair or an upgrade, this circuit board provides a reliable solution for ensuring efficient and safe ventilation in gas or oil-fired heating systems.
